单词 chlorite
释义

chloriten.1

Brit. /ˈklɔːrʌɪt/, U.S. /ˈklɔˌraɪt/
Etymology: < Greek χλωρῖτις (Pliny), name of some green stone, < χλωρός light green: see -ite suffix1.
Mineralogy.
A name applied to certain green hydrous silicates of magnesia and alumina occurring in ancient rock-formations, and forming the characteristic ingredients of chlorite slate. The name was taken as a specific one by Werner in 1789. In 1838 Von Kobell showed that Werner's name included more than one species, and restricted it to the hexagonal chlorite of St. Gothard, from which he separated Ripidolite: various other species have since been established, as Penninite, Delessite, Leuchtenbergite, Clinochlore, Chloritoid, etc., and as ‘chlorite’ has thus become a vague popular term, Dana has given the name of Prochlorite to the St. Gothard mineral on which Werner founded the species.
